Cucumber Scenario Outline

What is Scenario Outline in Cucumber?

Scenario Outline:

• It is a keyword provided in gherkin language.
• It is mainly used to execute the same scenario multiple times, with different combinations of input test data/values.
• Scenario Outline is a synonym of the keyword Scenario Template.
• Examples is a keyword and must be used in the scenario outline to pass the input data/values.

Demo on Scenario Outline:

Let's say I have 2 scenarios like below:

scenarioOutline.feature:

Feature: Demo on scenario outline
  Scenario: First scenario
    Given I am on home page
    When I search for "Nokia" mobile
    Then I should see mobile phones
  Scenario: Second scenario
    Given I am on home page
    When I search for "Samsung" mobile
    Then I should see mobile phones

Here,we observe 2 scenarios having same steps but with different input values.(nokia,samsung)

By using scenario outline we write above 2 scenarios into 1 scenario with different input values.

Scenario Template: Scenario outline example
  Given I am on home page
  When I search for "<mobile_company>" mobile
  Then I should see mobile phones
  Examples:
    | mobile_company |
    | Nokia                 |
    | Samsung            |
For above scenario, 

Observe we have used keyword Scenario Template and step definitions are implemented like below:

public class outLineStepDefinitions {
    @Given("I am on home page")
    public void iAmOnHomePage() {
        System.out.println("I am on Home Page");
    }
    @When("I search for {string} mobile")
    public void iSearchForMobile(String parameter) {
        System.out.println("I search for "+parameter+" mobile");
    }
    @Then("I should see mobile phones")
    public void iShouldSeeMobilePhones() {
        System.out.println("I should see Mobile Phones");
    }
}


Now execute the scenario:

We can also pass multiple arguments/test data/values in steps.
